Delisting Ag-Impaired Streams in Central PA

In 2019, the rapid stream delisting strategy was conceived during a pilot project aimed at prioritizing agricultural restoration projects using GIS. In 2020, partners including nonprofits, academic institutions, state, local, and federal governments together, and businesses rallied around using this data-driven approach to restore ecosystem health.

The focus is now on 57 streams across 7 PA counties, and partners have completed outreach to over 400 farmers in the region. As of the end of 2023, 229 high-priority projects are fully funded and are either complete, underway, or moving forward in 2023. With an additional queue of 50+ projects and support from a diversity of funding partners, the program is nearly 54% of the way toward achieving implementation targets. Targets include 35,058 acres of land treated with Best Management Practices (BMPs) and 1,675 acres of riparian forest buffers in the catchment areas which drain to the priority stream segments.

With long-term ecosystem health in mind, the project partners are committed to the long-term maintenance of projects. Partners coordinate volunteers on quarterly maintenance days to replace tree mortality, straightening/removing tree tubes and contracting with professionals where needed. Permanent conservation and preservation easements are also a priority for the next phase of the program.

This program aims to reduce agricultural impacts in local streams toward the tangible, policy outcome of “delisting” streams from the list of impaired waterways in Pennsylvania’s Integrated Water Quality Report. Collecting monitoring data on progress will help inform and change strategies; demonstrating improvements in fish and aquatic insect populations will motivate partners and farmers alike. Project partners are working with the PA Dept. of Environmental Protection to create monitoring plans for each stream which may include water chemistry analysis, assessment of Index of Biotic Integrity (IBI), and/or a Stream Habitat Assessment.
